Aren't you supposed to use the internal h264 parser to do the chunking before feeding it into the decoder if you choose to not use the built-in demuxers? (The built-in ones will automatically call the parser for you if you call av_read_frame() instead of av_read_packet().) Or in other words, is this in any way reproducible with avconv/avplay?
